The best time to extract loose teeth in children is during the period of tooth replacement just before the eruption of permanent teeth, but the exact time should be analyzed in conjunction with the actual condition of the patient. Loose teeth are a common physiological phenomenon in children during the alternation of permanent teeth and milk teeth, and most of them occur between the ages of 8 and 12. Before the extraction of the baby teeth, the patient can be observed for the presence of eruption of the permanent teeth in the lower part of the baby teeth. If the permanent teeth are already erupting, it is recommended that they be extracted as soon as possible to avoid blocking the normal growth of the permanent teeth. Secondly, if the loose milk teeth are accompanied by adverse symptoms such as tooth pain, chewing difficulty, gum redness and swelling, they should be extracted at the hospital’s dentistry department as soon as possible to avoid the occurrence of other oral diseases. Before receiving tooth extraction treatment, parents should fully communicate with their children to eliminate their fears and better ensure the smooth treatment.
